Holley aluminum LS valve covers will give your Chevrolet LS Series engines a totally new look. Manufactured from cast aluminum, they come in four different finishes, and feature a billet aluminum oil fill cap. Some valve covers in this series eliminate the need for the factory ignition coil bracket. Instead, the coils bolt directly to the valve covers for a nice angled look! Holley aluminum LS valve covers reuse the factory gaskets and bolts, will work with .750 in. lift camshafts using stock-style rocker arms, and fit all ignition coils with 72mm spacing.

Go Fast Bits Respons TMS direct-fit blow-off valves with TMS Advantage allows you to infinitely vary how much air is recirculated or vented to atmosphere. Simply by twisting the adjustment ring, you can change the sound of your BOV from silent to ear-shattering! GFB's patented venting bias adjustment system can be tweaked between full recirculation (silent) and full atmosphere (loud). With the Turbo Management System (TMS) technology, Respons BOVs can return the engine to peak boost up to 30 percent faster than a factory diverter valve when shifting gears, offers better throttle response, and unlimited boost-holding. If cars like yours typically suffer issues such as backfiring and stalling when using a fixed-ratio atmosphere-venting BOV, the Respons valves can help. By adjusting the venting bias to suit the car you can achieve a blow-off sound without having to put up with the issues.

Trail-Gear steering control valves function as orbital load reactive valves. These valves sense external forces placed on the system via the ram and react to them. If your steering and axle calculations are correct, the wheels will return to center. The ram you use with your orbital will determine the number of turns it takes to get from lock to lock.

Go Fast Bits' DVX takes the extremely popular DV+ diverter valve and adds dual venting outlets, along with GFB's patented venting bias adjustment system. So, not only do you get improved boost holding and throttle response, you have total control over your blow-off sound volume! The DVX is not just a noise maker (like BOV spacers); by modifying the valve operation method, it offers the same performance benefits that the DV+ does. It retains ECU control for the fastest possible operation. No other blow-off valve has the advantage of GFB's venting bias adjustment, allowing you to alter the blow-off sound simply by moving the adjustment lever. GFB's DV+ design solves the longevity and boost leaking issues that are common with factory diverter valves, and also changes the operation method to "pilot actuation" to ensure better performance on stock or modified engines. Furthermore, these benefits won't cost you a fortune! Rather than throwing the entire factory diverter valve system in the trash (like other manufacturer's "solutions"), the DV+ keeps what works and replaces what doesn't. Order the model recommended for your vehicle.

Go Fast Bits Respons TMS Universal blow-off valves with TMS Advantage are patented adjustable venting bias system diverter valves. GFB's Respons BOVs allow you to precisely control how much air expels from each of the two outlets, which is key for two reasons. First, you can adjust how loud the blow-off sound is--recirculate all of the air for silent factory operation, vent it all to atmosphere for maximum noise, or set it anywhere in between to suit your preference. Second, you get a blow-off sound without causing stalling, backfiring, or any other BOV-related issues, even on a car with a sensitive airflow meter (MAF). And this is accomplished by simply twisting the adjusting ring. GFB's Respons TMS Universal blow-off valves are not just noisemakers. They also offer better throttle response, faster boost recovery on gearshift, and unlimited boost-holding. Using GFB's TMS (Turbo Management System) principle, tests show that Respons valves can return the engine to peak boost up to 30 percent faster than a factory diverter valve when shifting gears.

The Hybrid valve is back! Go Fast Bits Hybrid dual outlet valves are three valves in one; full recirculation, full atmosphere, or 50/50 venting. In 1999, GFB's first Hybrid valve pioneered the dual port design, which was so successful, and the technology has since been adopted by most other brands. By "staging" the two venting outlets at low valve lifts most of the air is recirculated. As the car is driven harder, the valve opens further and more of the atmosphere venting port is exposed for a louder sound--a benefit that makes it possible to use these valves on cars with sensitive airflow meters that often suffer issues such as backfiring and/or stalling, whilst still achieving the signature blow-off sound. Go Fast Bits Hybrid dual outlet valves are direct-fit, bolt-ons with a range that covers a huge list of popular vehicles. Purchase the Hybrid model for your vehicle.

Go Fast Bits offers Mach 2 TMS Recirculating Diverter Valves for a variety of vehicles. It's the simple and essential modification for 30 percent quicker boost—utilizing proven TMS (Turbo Management System) technology to ensure dependable boost holding and optimum throttle response. If you don't need the patented venting bias adjustment feature of the Respons or Deceptor Pro, the Mach 2 is your answer. It's configured as a 100 percent recirculating valve (i.e. bypass, plumb back), and add-on kits are also available to convert to 100 percent atmosphere venting. Use the recirc model for direct factory replacement when you want the performance without the noise—or add the conversion kit when you want some noise with your performance! Factory bypass valves have two main shortcomings: they're typically designed to start opening above a certain pressure to protect the engine, and they're not optimized for throttle response. And you can't vent them to atmosphere without stalling your engine. The Mach 2 solves all of these issues. It can effectively hold unlimited boost (unlimited in that no turbo could ever produce enough pressure to damage it), and the TMS technology ensures maximum throttle response. And you CAN vent with the atmo conversion to atmosphere without stalling your engine. Product notes: * Recirculation model for direct factory replacement for performance without the noise * Atmosphere venting kits to convert the recirculating valve if you want noise with your performance * Like the Respons and Deceptor Pro II, the Mach 2 is available in a range of bolt-on kits for most popular turbo models * No additional adaptors, parts or vehicle modifications are required—simply remove the factory bypass valve and replace it with the Mach 2; it's that simple!

Go Fast Bits SV52 blow-off valves are more compact and offer more flow. Standing only 86mm tall including the weld-on adapter, the SV52s have an astonishing boost pressure rating of 300 psi, and feature a monobloc body design, CNC-machined from a single aluminum billet that ensures strength without adding unnecessary bulk. They are designed with an anodized piston bore that creates an extremely hard and low-friction surface on which the single-piece aluminum 52.5mm piston glides and will continue to do so over countless cycles. The piston also provides strength and reliability, something a diaphragm cannot match in a high-boost BOV environment. Go Fast Bits SV52 blow-off valves include two springs, plus a spring pre-load adjustment system, so you can dial it in for optimum throttle response and boost recovery after gearshift, without resorting to the costly hit-and-miss approach of purchasing extra springs.
